ADRENLN's probably right about not needing it, but knowiing the A/F ratio is correct would be somewhat of an influence to at least go do a Dynoday with an A/F check, then decide.
I highly reccomend a Dyno tune! I was running 13.15 with 239 hp and 264 ft lbs of tq and after the SCT dyno tune it made 50 more rwhp by 4300 rpms and 58 more tq at 4100 rpms and a peak gain of 25hp and 40 rwtq! Now running 264 rwhp and 304 rwtq on a aode equipped stang! Ran a new best of 12.99 at 101.64! and 60 ft dropped from 1.81 to 1.73! I have all the basic bolt ons and pan to get over 275 to 280hp from stock heads and cams in the vear future!

I'm going to go out on a limb and say yes, get it dyno'd. If you have the money, and an available dyno, you might as well.. if nothing else, for a baseline.
if you do get it dynoed it couldnt hurt anything. you will get a hp number, get yor a/f perfect, and in the process pick up a little power. dont go by what this one guy said, 50, hp and all that crap. i never heard that before. he must have been tuning a viper.
